The present invention relates to vessels used for carrying out chemical and metallurgical processes and more particularly refers to a vess serving for the reception of heavy loads of materials to be treated by such chemical and metallurgical processes. As a rule ores, metals, stones and earths are treated in such vessels in a wet state or by the application of heat. The present invention in a high degree is independent on such kinds of treatment as well as on the contents of the vessel and also on the form or the shape of the vessel, so that the invention may advantageously be used for various technical purposes.

A preferred construction of the invention consists in using together with the vessel a head acting upon'the contents of the vessel. Under the expression head an arrangement, similar to that used in the construction of machine tools and mounted above the vessel, is to be understood in which various operating members, as electrodes, agitators, scrapers, pipes for withdrawing and other members, are

be introduced into the material to be treated and be employed to heat and agitate the. material, and to free the latter from slags etc. In the head used according to the invention the operating members are mounted in tight bearings so that they may be lifted only or be rotated for instance in the case of the blades of an agitator. To use the operating members the freely movable vessel performs the necessary movement with regard to the operating members.

Moreover, in any desired position of height the vessel may completely be rotated and swung and tilted around a large angle respectively with uniform Due to this novel arrangement the-vessel may also simultaneously perform two 'or even three movements. For instance rather simple means the vessel may ing be lifted and if desired also rotated. By means of the invention, therefore, a support for a vessel is provided the upper portion of which, being of particular importance for the manipulation, not only is freely accessible and is also movable in all directions, but in which, moreover, gears, at least gears arranged in the operating space, are completely dispensed with. In all operating conditions the vessel practically may be so treated as being weightless. Consequently the vessel may be loaded to any desired degree.

The invention will be further described, embodiments shown in the drawing, and finally pointed out in the claims. I
